One, the fact that they say casual games cost "1 million euros to 4 million, depending on how many platforms they're being created for" should indicate that casual != (or =/=) Wii game. In fact, it says just the opposite because it indicates that those games are often being ported to other systems as per the bolded part.
Two, no where in there does it ever state that the expensive games are losing money. It only says they are funded by cheaper games. As has been said, this merely sounds like goo dbusiness sense.
Three, and this is important as many people don't nerstand big business, even if the PS3 and 360 games were losing money on the whole there is a very good reason why the company still supports them. At the worst, these potential loss-leaders put their name out their and give them brand power that will essentially act like advertising. If someone enjoys an Ubisoft game on the PS3 that fails to make a profit they are still more likely to buy an Ubisoft product than before. Maybe it will be one of the profitable casual games, maybe it will be one more sale towards making the big budget PS3/360 games profitable.
Either way, as a business they wouldn't make these decisions if they weren't at least potentially profit-making endeavors. That is simply not how corporations opperate. Some way, some how, they mean to gain money through every action they take (even if they aren't successful at it). And their shareholders wouldn't have it any other way.
